I would never give anyone direct grammar advice on this forum.
Most people don't care about grammar, in any situation, so this is *my* issue. In a lot of cases, poor grammar is some form of learning disability; in others, poor teaching.
Just saying it bothers me to see it, as it seems to be a growing problem, everywhere, even in professional contexts, as so many of you have mentioned.

I am glad Veronica is inspiring young writers to learn the correct usage of grammar, in a way that makes it useful. When I first started teaching English, I was very much against direct teaching of grammar rules, because as a Special Ed teacher, it just never worked. But, I developed some strategies that worked in the context of some pretty detailed and creative writing pieces. Not everyone learned everything they needed to, but it didn't feel painful, in the way it had in the past.
